Prince Harry and Meghan Markle were in attendance at Kevin Costner‘s big charity event.

On Friday (September 22), the 68-year-old Yellowstone actor hosted the One805LIVE! Fall 2023 Fundraiser at his beachfront estate in Santa Barbara, Calif.

The Duke and Duchess of Sussex attended the event alongside Oprah Winfrey.

Kevin is an ambassador for One805, which provides financial aid and mental health support to first responders.

During the event, Harry and Meghan appeared onstage and presented Kevin with an award.

Kevin‘s ex-wife Christine Baumgartner was also listed as a host for the event on the One805, but it’s unclear if she was in attendance as she didn’t appear in any photos.

Earlier in the week, it was revealed that Kevin and Christine, 49, had settled their divorce.
